The jaw crusher processes rock to 5 7 inches, which is then stockpiled on the surge pile for the finishing plant. Stephanie Poole, Mining Engineer and Pit Supervisor for Savage Stone, explained that the quarry has exhausted its pit boundaries to the north and west, so expansion is moving to the south side of the pit and into lower levels of ...
The Aitik mine has set a long term goal to raise production from 36 to 45 million tons of crushed ore by 2020. To achieve this growth and improve the consistency and reliability of production at the same time, Boliden has invested in a completely new crushing plant with two spindle crushers. In its annual report the company states that this massive investment will ensure more reliable production planning, lower maintenance costs, better predictability and better profits. Right now we are getting a good price for what we produce. That gives us the opportunity to invest. But one big challenge is that we are greatly increasing the area of mining, which also involves high costs. We constantly have to fine tune our mining operations so that we can increase production using our existing equipment. The new crushing plant will enable us to do that, says Larsson. Obtaining the permit to expand also placed big demands on the ecological sustainability of the Aitik mine. We are leading the...

Larsson has a great deal of experience in the industry. He has done everything from operating mining machinery to supervising maintenance and installation. He has supervised the crushing project and been involved in commissioning. Its fantastic that we have been able to invest in a totally new plant, where everything is well planned and we have plenty of access to the equipment. He is especially pleased with the completely new feed system. We originally had inclined apron feeders. They were unreliable in every way. These are the first conveyors that are completely horizontal. And they look great! The feed system was designed by in the USA, and is a proven design with many systems already in use around the world. adapted the system to suit the particular needs of the Aitik mine. This work was done in close collaboration with Bosch Rexroth, which supplied four hydraulic Hägglunds CBm motors. One of the reasons why Boliden decided to invest in apron feeders with direct...
The new plant was commissioned in June 2018 and the Aitik mine is now running at full production capacity. After a few weeks of testing we went on summer vacation. I was away for five weeks and everything worked perfectly! The plant has now processed more than six million tons of ore and there has not been a single incident. The fact that production is running so smoothly at this early stage is an excellent result. Especially when the plant was custom built specifically for our needs. The drive systems take up minimal space and allow fast replacement of components, thanks to the splined couplings. Larsson reckons they make installation incredibly easy. The main benefits are that we have improved availability while reducing maintenance costs. The hydraulic drives provide better access from the sides and make the plant easier to maintain. The way things are looking now, we wont need to work on them, but if we do have to replace anything we have really good access. Another big adva...
